1,5-Naphthalenedisulfonic acid CAS 81-04-9
ʻO 1,5-Naphthalenedionic acid nā keʻokeʻo e like me ka pāpaʻi keʻokeʻo (me nā molekala ʻehā o ka wai aniani). Ka helu hehee 240-245 ℃ (anhydrous). Hiki ke hoʻoheheʻe ʻia i ka wai a me ka ethanol, ʻaʻole hiki ke hoʻoheheʻe ʻia i ka ether. Hoʻohana ʻia ka 1,5-Naphthalenedionic acid ma ke ʻano he mea waena no nā kala. Hoʻohana ʻia no ka hana ʻana i nā mea waena e like me 1,5-dihydroxynaphthalene a me nā waikawa amino.
